Agame cost $30 and a stoe bought it and sold it for $50. what is the percent need asap!

67%

Step-by-step explanation:

Cost plus markup = selling price.

Here, the cost was $30 and the selling price was $50.  Subtracting $30 from $50, we get $20, which was the dollar amount of the markup.

We now compare this $20 to the original cost ($30):

$20

* 100^ = 67%

$30

The markup, as a percentage, was 67%.

answer: options

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
